UNIPOLAR LINEAR ELECTRIC MOTOR Russian patent published in 1997 - IPC

FIELD: electric engineering, vehicles for freights. SUBSTANCE: moving part of device has magnetic field source which has upper and lower sections between which power current conductor 3 with current pickups 4 and 5 is located. Said current pickups are mounted on ends of power current conductor 3 and provide electric contact to fixed current conductors 6 and 7. In addition power supply system has current pickup 8 which reads voltage from contact power supply wire 9 and transmits it to controlled converter 10 which transforms power supply line voltage to low voltage. Heavier current from output of converter 10 is fed to power current conductor through supplying current pickups and corresponding parts of fixed current conductors 6 and 7 and current pickups 4 and 5. Traction force is generated by interaction between magnetic field source and currents in power current conductor 3 and fixed current conductors 6 and 7. EFFECT: increased functional capabilities. 6 cl, 7 dwg
